Which gas law tells you that?

Mixing takes place either because you've got turbulent flow as the
second gas comes in or through diffusion afterwards. If you have a
smooth incoming stream mixing takes place mostly through diffusion, and
that isn't instantaneous. The rate of diffusion across a boundary is
proportional to the difference in partial pressures at that boundary.

Since you're telling the story in this context, obviously the
measurement was dead on. Which proves that that time, the measurement
was dead on.

Thanks for your replies. Unfortunately, they helped me not at all --
didn't need a Nitrox primer. I guess I buy an analyzer or just wait
and see if a reliable one is on hand when I get there, before buying
the Nitrox package.

May of 2003 they had a color code system I thing green was 32% and
yellow was 36. At the bottel pickup in the parking lot there was a O2
analyzer by taped to the door, by the dock there was one on the wall.
the o2 analyer was not off it matched my O2 analyer. But becuase
there are so many people diving it is best that you check your tanks
ahead of time. by the way they did not like when we put our BCs on
the tank before the loaded the tank on bord.

Thanks, Yankeediver. Exactly what I wanted to know.
